IMPROVEMENT IN ClDER-MILLS.

Specification forming part of Letters Patent No. 149,214, dated March31, 1874; application filed February 21, 1874.

To all 'whom 'it may concern Be it known that we, THOMAS A. GALT andGEORGE S. TRACY, of Sterling, in the county of VVhitesides and State ofIllinois, have invented a new and valuable Improvement in Cider-Mills5and We do hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeing had to the annexed drawings 'making a part of this specification,and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a longitudinal sectionalview of our cidermill. Fig. 2 is a transverse sectional, and Fig. 3 aplan, View of the same. Figs. 4 and 5 are detail views of the same.

This invention has relation to mills for grinding and pressing applesand other fruits; and it consists in a novel construction of thegrinding and crushing rollers for the purpose of facilitating thereduction of the fruit, said rollers being respectivelyY composed ofconical frustums, firmly secured together upon a shaft, and presenting avery large reducing-surface on a compa at-ively short roller. It alsoconsists in the novel construction and arrangement of a hopper, withconcave plate, slide, and a slicer, as will behereinafter more fullydescribed.

The following is a description of our iniprovements In the annexeddrawings, A designates the frame of the mill; B, the floor upon whichthe pomacereceiver is supported, and O a strong casting, which is boltedfirmly to one end of the frame A, and through which the followerscrew Dis tapped. E E designate the improved crushing-rollers; F, a rotaryslicingdrum, and G the hopper, which latter is bolted to the upper endof a cast-iron box, H, containing said rollers and drum, as shown in thesectional view, Fig. l. The roller E is applied on a shaft, a, havingits bearings in boxes I) b, and carrying on one end a spur-wheel, c, anda hand-crank,c1, and also a pinion, c1. The wheel c engages with theteeth of a pinion, c, which is keyed on the shaft e', on which theroller E is applied, which latter roller receives a more rapid rotarymotion than the roller E. The pinion c1 engages With a spur-Wheel, c2,keyed on the shaft f of the slicing-drum F. Inside the box H, andproperly secured thereto, is an inclined plate, h, arranged so as tonearly touch the slicing-blades t' ,as they revolve; and on the oppositeside of the drum F to this plate is a concave plate, h', which forms athroat, j, in which the slicing takes place. Above the drum F is aslide, J, the vertical portion of which lies as close as practicable toplates h h and said drum. This slide has a row of holes through it forreceiving a pin, 7s, by means of Which the slide can be fixed to a lipformed on one side of the box or housing H after this slide is properlyadjusted. By adjusting slide J, the size of the entrance to theslicing-drum can be increased or diminished as it may be required tofeed fasteror slower. Each one of the grinding and crushing rollers ismade up of conical frustums lu n, connected together by rabbeted joints,as shown in the enlargedl sectional View, Fig. 4L; and these frustumsare put together so as to form alternate ridges and Valleys, theirsurfaces being ribbed, as shown, or in any other suitable manner. At theends 0f the rollers plates m m are applied, so that the frustums can befirmly secured together by means of nuts p, applied on thescrew-threaded portions of their shafts.

Rollers thus constructed can be shortened or lengthened at pleasure bytaking from or adding to them the frustiuns, and thus We can have alarger or smaller mill, as may be required. The ridges of one roller arereceived into the valleys 0f the other roller, thereby bringing theribbed surfaces in close relation, so that they will grind as well ascrush the fruit passed between them.

The shaft a of the corrugated roller E is journ aled in bearings 1' r,which are adjustable in boxes s s by means of set-screws t. This rollerE can thus be adjusted nearer to or farther from the roller E, accordingto the degree of ineness required of the pomace. Roller E has abalance-wheel, W, keyed on oneend of its shaft, for steadying the motionof the mill.

The pomace is cleared from the rollers E E by means of two scrapers, LL, whose upper edges correspond in their shape to the angular surfacesof these rollers.

What we elaiin as new, and desire to secure by Letters Patent, is-

1 In a cider-mill, the crushing and grinding rollers, composed ofconical frustnrns a a, connected by means of rabbeted joints, heads m,and nuts, substantiall5r as described.

2. A erushin g and grinding roller having alternate ribbed ridges andvalleys, the same composed of the attachable or separable frustunis n,as shown and described.

3. rlhe combination and arrangement of the hopper Gr with concave plateh', slide J, and slicer F, all constructed as and for the purpose setforth.

y In testimonT that we claim the above we have hereunto subscribed ournames in the presence of two Witnesses.
